摘要
本文根据上海1984年有代表性的154天,进行影响上海城市热岛强度的回归分析。发现城市热岛强度与太阳直接辐射日总量为正相关,与风速和云量为负相关。太阳直接辐射日总量对城市热岛的影响与城乡下垫面的反射、吸收和增温、冷却的差异有关。我们又用气象卫星资料,结合实测的太阳辐射日总量和城、乡的气温、云量、风速等气象资料,对上海1984年不同季节城市热岛的若干典型个例进行分析,说明上海城市太阳直接辐射日总量对上海城市热岛形成及其强度变化起着重要作用。
In order to clarify the effect of solar radiation on the intensity of urban heat island, we survey the daily data in the year of 1984 of Xinzhuang(rural) and Longhua(urban) and use 154 days as regression samples- The regrassion equation (see Eq. 1) shows that the direct solar radiation has a. positive effect on the intensity of the Shanghai urban heat island but the wind velocity and the cloudiness have a negative effect on it. By using the records provided by satellites and the simultaneous observational data of solar radiation and relative meteorological factors, we analyse several typical cases of Shanghai urban heat island in different seasons.
